我使用Capistrano 2,Unicorn,Nginx部署了我的RoR 4应用程序.
问题是我获得404资产(样式表,javascripts).

这是Nginx访问日志：

89.0.40.233 - - [16/Mar/2014:08:24:26 +0000] "GET /stylesheets/application.css HTTP/1.1" 404 650 "http://host.cloudapp.net/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_2) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/33.0.1750.149 Safari/537.36"

我的资源位于app文件夹中：

azureuser@host:~/apps/testify/current/public$ls -a assets
.                                                    application-d65a0eaefe6ca2eef9400045f94ab52b.js
..                                                   application-d65a0eaefe6ca2eef9400045f94ab52b.js.gz
application-71e2591e9586afebf3fb4ff70aaae199.css     manifest-a348973e84698f7d898e8021bd6e5388.json
application-71e2591e9586afebf3fb4ff70aaae199.css.gz

我的Nginx配置：

upstream unicorn {
  server unix:/tmp/unicorn.testify.sock fail_timeout=0;
}
server {
  listen 80 default deferred;
  root /home/azureuser/apps/testify/current/public;
  location ^~ /assets/ {
    expires max;
    add_header Cache-Control public;
  }
  try_files $uri/index.html $uri @unicorn;
  location @unicorn {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://unicorn;
  }
  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

我从哪里开始看？
